Product Description

The EcoFlow DELTA 3 Max is a high-capacity 2048Wh portable power station designed to provide reliable backup power at home, at work or away from mains electricity.

2400W Rated AC Output

The DELTA 3 Max delivers 2400W rated pure sine wave AC output through four 230V AC outlets, allowing it to power a wide range of compatible household appliances, electronics and equipment.

EcoFlow's X-Boost 3.0 technology supports selected compatible appliances rated up to 3200W.

X-Boost does not increase the normal rated AC output beyond 2400W and may not be suitable for every appliance.

Fast AC Charging

EcoFlow's X-Stream fast-charging technology provides up to 1800W AC charging input.

Under optimal charging conditions, the DELTA 3 Max can recharge from approximately:

0–80% in 51 minutes

Solar Charging

For renewable and off-grid charging, the DELTA 3 Max supports up to:

500W Solar Input

EcoFlow states that suitable 500W solar input can charge the battery from approximately 0–80% in 3.43 hours under favourable conditions.

Generator Charging

The DELTA 3 Max supports compatible EcoFlow generator charging.

With suitable 2400W generator input, EcoFlow states that the battery can recharge from approximately 0–80% in 51 minutes.

Compatible EcoFlow Smart Generators are sold separately.

Alternator Charging

The DELTA 3 Max can also be charged using the EcoFlow 800W Alternator Charger.

Connection requires the:

EcoFlow Alternator Charger XT60 Output Cable

The required cable is sold separately unless included as part of a specific bundle.

Reverse charging to the vehicle battery and battery-preservation functions are not available through the DELTA 3 Max XT60 connection.

<10ms UPS Backup

The DELTA 3 Max provides <10ms automatic UPS switchover, allowing compatible equipment to transfer rapidly to battery power when mains electricity is interrupted.

This makes it suitable for compatible equipment such as:

• Computers
• Wi-Fi and fibre equipment
• Networking equipment
• NAS systems
• Servers
• Communication equipment
• Other suitable electronics

Connected equipment must be capable of tolerating the DELTA 3 Max's transfer time.

Long-Life LFP Battery

The DELTA 3 Max uses automotive-grade full-tab LFP / LiFePO4 battery cells with EcoFlow's intelligent Battery Management System.

The BMS monitors key battery conditions including state of charge, state of health and temperature.

EcoFlow also uses an EV-grade cell-to-chassis structure designed to improve protection and structural durability during transport and everyday use.

Quiet Operation

EcoFlow's X-Quiet thermal-management system allows the DELTA 3 Max to operate at ≤25dB at a 600W load under EcoFlow's specified test conditions.

Smart App Control

Built-in 2.4GHz Wi-Fi and Bluetooth 5.0 connectivity provides monitoring and compatible controls through the EcoFlow App.

The app can be used to monitor information such as battery status, input power, output power and compatible charging settings.
